SPECIFICATION forming part of Letters'Patent No. 463,250, dated November 17, 1891.

Application nea una 7, 1891.K

To all wiz/0m it may concern.

Be it known that I, ELL/is B. lpoorMAN, a citizen of the United States, residing at the city and county of New York, in the State of New York, have invented certain new and useful Improvements in Locking Devices, of which the following is a specification, such as will enable others skilled in the art to which The primaryobject of this invention is to although it is evident fronrthe following descriptionfof the construction and operation other purposes than those herein stated.

The said invention is fully disclosedjl; the' following specification, of which the accompanying drawings form a part, wherein simi;-

equivalent parts wherever found throughout the several views', and inv whichv,

Figurev 1. represents in eentralvertieal Secto a coin-holder or pocket-bank Fig. 2, alike View of a modified form thereof as applied to ofthe construction'shown in Fig. 2.

' Referring to the drawings, the numeral 41,

closed at the top and provided at its lower end with'an interior screw-thread 2, adapted to receive a plug or end piece 3, provided shown. This plug 3 is provided with an ontwardly and downwardly extending spring portion orlug 4, adapted to spring into anden-v ter a recess or cavity 5, formed in one side of home in such Vmanneras to prevent the same from being unscrewed so long as suchspring The tube 1 is elongated, as shown, for the purpose of holding coins, and is provided near its upper end with 'a ,slot deepening 6 .for their reception.. iVithin the same, and preferably secured to the plug 3, is a spiral spring 7, provided at its upper endl with a movable head or follower 8, provided withdepending sides 9, which are also preferably secured to said spring 7. Said plugor end piece 3 is preferably made hollow, asshown, and the Serial No. 384,135. (No model.)

vspring-lug 4 thereof may be formed integral Coins 10 being inserted into the holder onev by one throughthe slot or opening 6, the fol- I lower, 8 is depressed thereby until the downwardly-depending sides 9 thereof pass over the spring-lug 4 and depress the saine infand the coins, removed.

` In the modification shown in Figs. 2pand3 -I have shown my invention as adapted for use as a bottle-loel'r, the neck of the bottle being equivalent to the tube 1,-and being in thisins'tance provided with right-angled slots 11, into which slide studs4 or projections 12, formedon the plug 3, the two together, forining a bayonet-joint, which -tak'esth'e place of the screw-joint shown in Fig. 1. In thisform of construction'the head or follower S is nor- Inally, held imposition, as shown, bya spring y 7, so that the depending sides thereof barely allow the spring4L to enter the slot5, and this head or followeris in thiscase provided with an interior hollow extension 13, inclosed with-` inthe spring 7, which extension 13 is provided with a longitudinal slot. 14, connected with an inclined peripheral slot 15, ending in a short straight peripheral slot 16,and in the end'of the plug 3 is a key-hole 17. The operation of this form ofdevice is as follows: A

` key of'l suitable form being inserted through the hole 1'( -until the bit thereof passes through the slot 14C into the slot 15, upon tu rning the same the bit passing along the. inclined peripheral slot 15 intothe straight slot 16 pulls thefollower or head 8 upward unt-il the sides 9 thereof, pressing the'spring 4 in-` wardly, at'lastrelease it from the cavity 5, when by simply turning the plug 3 until the vstuds 12 enter the upright portions of the IOO . and means for depressing the follower, subadapted to enter the other and elose the same, .j

tion, its construction and' operation, what I e1aim,and desire to secure by Letters Patent, 1s

1. The combination, in a locking .device-ofa tube, a plug therefor, one of said parts be. ing provided with a spring-'lug and the other vwith a cavity or recess to receive the same, the pluginr and tube being adapted to llock together'vby e rotative movement, a. follower orl headv normally clear of the spring-lug, but adapted to release the same when depressed,

stantia-llyas shown and described.

2'. ,In a locking device, the `combination of a tube lor casing closed at one end, a plug said tube and plug being provided one with arecess orcavityand the other with aspringlug adapted At0 epterflthe same by 'a rotative Wmovementrotthe parts, so as to prevent the reverse rotation of the same, and a movable head vor follower adapted to release the springlug from the cavity when depressed,v after which the parts may be'separated, substantially as shown and described.
